We present surface brightness profile decompositions for a
large number of spiral and lenticular galaxies. For an initial
sample of 659 galaxies, we find that the observed V brightness
profiles of 620, or 94of a de Vaucouleurs law bulge and an inner-truncated exponential
disk. We find no correlations between the quality of fit and
either the morphological type or the inclination of the system. In
particular, the adopted decompositions work equally well for
barred and unbarred galaxies. About 25are best fit with an inner-truncated exponential, suggesting
that such truncations are both real and relatively common. We
compare our fitted profiles to those of other authors and interpret
some differences. Finally, we re-address Freeman's 1970 suggestion
that the disk central brightness parameter is substantially
constant among spiral and lenticular galaxies.
